Why are floor plan theme colors in graphic views inconsistent?

We are running Application 10.5 and Platform 3.5.0.1. We are noticing in most themes, both OOB and custom, that the colors change in the graphic view in all of the forms we tested. Is there a way to make the colors stay consistent?

Also, we have a theme that categorizes vacant space to four classifications. Each of the four classifications have default colors. The graphic view never brings up all four default colors at once. It may choose three default colors and seemingly randomly chooses the other. Why?
